Abstract

A propulsion system for an aircraft includes an electric generator and a turbomachine. The turbomachine is configured to be mounted to a first wing of the aircraft and is operable with the electric generator. The propulsion system additionally includes a first propulsor mechanically coupled to a shaft of the turbomachine and a second propulsor assembly configured to be mounted at a location away from the turbomachine and the first propulsor. The electric generator is in electrical communication with the second propulsor assembly for powering the second propulsor assembly.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]The present application claims filing benefit of U.S. Provisional Patent Application Ser. No. 62 / 304,450 having a filing date of Mar. 7, 2016 and which is incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]The present subject matter relates generally to a propulsion system for an aircraft, and an aircraft including the same.BACKGROUND OF THE INVENTION[0003]A conventional aircraft generally includes a fuselage, a pair of wings, and a propulsion system that provides thrust. The propulsion system typically includes at least two aircraft engines, such as turbofan jet engines. Each turbofan jet engine is mounted to a respective one of the wings of the aircraft, such as in a suspended position beneath the wing.[0004]For small passenger aircraft, the two aircraft engines may be relatively small, low thrust generating aircraft engines. However, as is generally understood, the relatively small aircraft engines may not be ...
